IMPROVEMENT IN VEHlCLE-AXLES.

Specification forming part of Letters Patent No. 169,845, dated November9, 1875; application filed August 26, 1875.

To all whom it may concern:

Be it known that I, CLINTON W. RICHARD- soN, of Flushing, in the countyof Queens and State of New York, have invented a new and usefulImprovement in Axle-Trees for Wagons and other wheel-vehicles; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawing, which forms part of this specification.

This invention relates to axles for vehicles of, different descriptions,in which the axle is composed of ametallic shell or tree-piece having aconcave U-shaped crosssection journalpieces fitted therein, and made ofround bar steel with collars, and secured within the ends of the shellby brazing or welding, and, if desired, a wooden filling to the shell,substantially as described in Letters Patent No. 152,974, granted to R.W. Davis, A. W. Davis, and E. Eldridge, July 14, 1874.

The invention consists in a grooved construction of the collars on thejournal-pieces with the ends of the metallic shell bent to enter saidgrooves, whereby said shell is more effectually retained in position andbraced at its ends, and the axle-tree, which combines lightness withstrength, is generaldyimproved.

Figure 1 represents a view, in perspective, of the one end of theimproved axle or axletree before fitting the groovedcollar of thejournal-piece over the end of the shell. Fig. 2 is a verticallongitudinal section of the same after the metallic shell or tree-piecehas been entered within the grooved collar of the journal-piece. v

A is the metallic tree-piece, and B one of the journal-pieces at the oneend of the same. The tree-piece A consists of a shell of springsteel ofU shape in its transverse section, which form may be given it by puttingit into adrop and swagin g or striking it up'into shape.

It may be made either straight or slightly arched in a longitudinaldirection. Each journal-piece B may be of round steel with the journalturned and acollar, b, shrunk orforged on it, said collar forming ashoulder at the end of the tree-piece for the hub of the wheel to bearagainst. These journal-pieces B are fitted snugly into the U-shaped endsof the tree-piece, and are united therewith by weld, ing or brazing,but, preferably, by brazing.

Before uniting, however, the ends of the treepiece and thejournal-pieces, the ends of the metallic shell or tree-piece A areturned in, so as to continue their circular form beyond the half'circle,for the purpose of'entering them within the grooves c in the inner faceof the collars b on the journal-pieces, whereby the shell A is moreeftectuallyretained in position and braced at its ends, and thetree-piece and journal-pieces more firmly secured or combined; also, theaxle generally improved. A wooden filling, shaped to fill the concavityof the tree-piece, and projecting slightly above it, may be com bined,if desired, with the trough-shaped tree-piece and journal-pieces fittingtherein. to preserve the U shape of the tree-piece, and to give itstiffness and strength in a lateral direction; but in many cases thebent shape of the metallic shell or tree-piece will give sufficientstiffness Without the Wooden filling.

I claim- The journal-pieces B, having the collars b, constructed withthe grooves c, in combina tion with the tree-piece A, consisting of ametallic shell, U shaped in cross scction, and having its ends bentaround the shanks of the journals and. fitted within the grooves c inthe collars b, substantially as shown and described.
